So much for a good faith discussion here. I don't appreciate that you tell me to "get a grip". You're not steelmanning. Instead, your reaction comes off as a knee jerk reaction. There are enough communities where I have to come up with defenses to deal with that nonsense. Don't do it here please.

US melatonin measured dosage can be 4x as much as what is reported [1, 2].

Also 0.3 mg is the recommended dose [4]. A lot of doses in the US are way higher than 0.3 mg. In the Netherlands it's stupidly easy to find 0.1 mg doses (e.g. at the Kruidvat or at the Etos). It's in part why I never looked further.

And since you're new here (55 days ago, 13 karma as of writing). I strongly recommend you to read the HN guidelines [3]. All people who are on HN should follow them, not knowing them degrades the community experience that we're having here.

There are a few others that apply as well.
